How is the triangle formula derived from the area of rectangles?
The area of a triangle is expressed using the formula A=(1/2)(bh) Where A is area Where B is length of the base of the triangle. Where H is the height of the triangle. The area of a rectangle is A=BH, Where B is the length of the base of the rectangle. Where H is the height of the rectangle. Because a triangle, essentially, is a half of a rectangle, you find the area of the whole rectangle that the triangle comes from, then divide that in half.
Teach a child area of triangle without formula?
You will have to use a formula, but this can easily be derived for the special case of a right triangle. If you divide a rectangle by a diagonal, you divide it into two congruent triangles, therefore, the triangle has half the area of the rectangle, that is, 1/2 times base times height.
Why is the area of the triangle half the base times the height?
Because a triangle is half of a rectangle. The area of a rectangle is length times width, the area of a triangle is half that.
What is the formula of finding an area?
in finding the area if a square or rectangle multiply the length and width, for a triangle, multiply length and width divided by two.
Who invent the formula to find the area of rectangle?
There are several different formulae for the area of a triangle - depending on the available information - and these were invented by different people.

What is the formula of an area of a rectangle?
an area of a triangle is the three sides comined
Which formula for the area of a parallogram is similar to a rectangle circle triangle ellipse or trapezoid?
Rectangle Area of parallelogram = Base * Height Area of rectangle = Base * Height
How do you find the area of a rectangle with a triangle attached to the side?
you split your shape in half, (The rectangle and the triangle), by putting a line through it and then calculate the area of the rectangle and then calculate the area of the triangle, half the area of the triangle then add the area of the triangle and the rectangle together!Then you should have your answer!
What is the formula for the area of a rectangle with in a triangle when given only the lengths of the sides of the triangle?
area of the rectangle=l*b therefore ans = tere liye ...... jannate sajau mei tere liye....

What's area formula of an irregular polygon?
Divide polygon into rectangles, then use area formula for rectangle: Area = (high a + high b) / 2 x length c If polygon contains triangle, then triangle can be considered as rectangle with one of its side length is close to zero.
What is the relationship between the area of a triangle and a rectangle?
The relationship between the area of a triangle and a rectangle is a Triangle is base times height divided by 2. Area of a rectangle is length times height.
How is the formula for the parallelogram related to the area formula of the rectangle?
The area formula for the parallelogram is related to the area formula for a rectangle because you can make the parallelogram into a rectangle to find the area.
How is the area of a triangle related to the area of a rectangle?
It's half the area of a rectangle
Which is greater 3ftx2ft rectangle or a triangle with base of 3 ft height 5 fft?
The formula for the area of a rectangle is length x width; the area of a triangle is half the product of the base and the height. Thus, the rectangle has an area of 3 x 2 = 6, while the triangle has an area of (3 x 5) / 2 = 7.5. 7.5 is greater than 6, so the triangle is larger.
Why is the area of the triangle half the base times the height?
Because a triangle is half of a rectangle. The area of a rectangle is length times width, the area of a triangle is half that.
